Abstract

The degree of elliptical polarization of intense short laser pulses is shown to be related to the timing of strong-field nonsequential double ionization. Higher ellipticity is predicted to force the initiation of double ionization into a narrower time window, and this 'pins' the ionizing field strength in an unexpected way, leading to the first experimentally testable formula for double ionization probability as a function of ellipticity.

Effects of Elliptical Polarization on Strong-Field Short-Pulse Double Ionization

Journal Article Xu, Wang ; Eberly, J H - Physical Review Letters

We predict new end-of-pulse behavior in high-field atomic double ionization. Calculations of atomic electron trajectories in short intense laser pulses confirm our analysis of elliptical polarization. We exhibit a four-band structure in ion momentum distributions under various ellipticities, and predict that sequential and nonsequential double ionization can be cleanly distinguished under elliptical polarization.

Transition of recollision trajectories from linear to elliptical polarization

Journal Article Li, Yingbin ; Yu, Benhai ; Tang, Qingbin ; ... - Optics Express

Using a classical ensemble method, we revisit the topic of recollision and nonsequential double ionization with elliptically polarized laser fields. We focus on how the recollision mechanism transitions from short trajectories with linear polarization to long trajectories with elliptical polarization. Furthermore, we propose how this transition can be observed by measuring the carrier-envelop-phase dependence of the correlated electron momentum spectra using currently available few-cycle laser pulses.

Resonance enhancement of nonsequential double ionization by a magnetic field

Journal Article Hongyun, Li ; Laboratory of Optical Physics, Institute of Physics, Chinese Academy of Sciences, Beijing 100190 ; Jing, Chen ; ... - Physical Review. A

We investigate nonsequential double ionization (NSDI) of helium by using an additional magnetic field parallel to the polarization of the laser pulse. By exploring the ability of a magnetic field for focusing the selected trajectories that contribute to the NSDI, we have found that the yield of NSDI, as a function of the magnetic-field strength, shows different behavior for different laser intensities. As a result, an additional magnetic field provides a way to identify that the NSDI mechanism of laser-assisted collision ionization begins to play an important role as the laser intensity increases.

Nonsequential double ionization of D{sub 2} molecules with intense 20-fs pulses

Journal Article Sakai, Hirofumi ; Larsen, Jakob Juul ; Wendt-Larsen, Ida ; ... - Physical Review. A

The kinetic-energy distribution of D{sup +} fragments obtained from the ionization of D{sub 2} molecules with intense 20-fs pulses includes a high-energy component extending up to {approx}10 eV. These fragments are only present for linearly, or slightly elliptically, polarized light. Both the maximum kinetic-energy and the ellipticity dependence are consistent with nonsequential double ionization caused by recollision.

Controlling Nonsequential Double Ionization in Two-Color Circularly Polarized Femtosecond Laser Fields

Journal Article Mancuso, Christopher A. ; Dorney, Kevin M. ; Hickstein, Daniel D. ; ... - Physical Review Letters

Atoms undergoing strong-field ionization in two-color circularly polarized femtosecond laser fields exhibit unique two-dimensional photoelectron trajectories and can emit bright circularly polarized extreme ultraviolet and soft-x-ray beams. Here, we present the first experimental observation of nonsequential double ionization in these tailored laser fields. Moreover, we can enhance or suppress nonsequential double ionization by changing the intensity ratio and helicity of the two driving laser fields to maximize or minimize high-energy electron-ion rescattering. Our experimental results are explained through classical simulations, which also provide insight into how to optimize the generation of circularly polarized high harmonic beams.
